[libvirt] [PATCH 0/7] documentation improvements - again
by Claudio Bley 01 Feb '13

01 Feb '13

Hi. The first two patches are aimed at avoiding generation of empty argument description lists, which might happen if a function has no documentation for some argument or its return type. This was happening with virTypedParams* functions (see https://www.redhat.com/archives/libvir-list/2013-January/msg01428.html) Patch #3 is just a small cleanup, since a table is not the right thing to use and it looks better in some circumstances. Patch #4 sports processing of code blocks embedded into comments. Basically, it is similar to markdown syntax, except that you only need to indent your code with 2 spaces. Patch #5 prepares for the later patches being able to distinguish between different <pre> blocks. Patch #6 and #7 are pretty much self explanatory, I guess. Note, that SHJS's license is GPLv3. Claudio Bley (7): docs: don't write out empty info attributes for function arguments docs: only generate function argument info for args with a description docs: use a div instead of a 3 column table for undisclosed notices docs: process code blocks similar to markdown docs: add class "description" to div's containing descriptions docs: define style of code blocks inside descriptions docs: syntax highlight code blocks using SHJS docs/apibuild.py | 8 +- docs/libvirt.css | 8 ++ docs/newapi.xsl | 209 +++++++++++++++++++++++++++++-------------------- docs/page.xsl | 5 +- docs/sh_c.min.js | 1 + docs/sh_emacs.min.css | 1 + docs/sh_main.min.js | 4 + 7 files changed, 148 insertions(+), 88 deletions(-) create mode 100644 docs/sh_c.min.js create mode 100644 docs/sh_emacs.min.css create mode 100644 docs/sh_main.min.js -- 1.7.9.5

[libvirt] Canonical citation for Libvirt
by Lempereur, Brett 01 Feb '13

01 Feb '13

Hi, Is there a canonical paper I can cite for Libvirt in academic publications? The best I've found so far is Bolt, M., Birkenheuer, G., Niehörster, O., & Brinkmann, A. (2010). Non-Intrusive Virtualization Management using Libvirt. Proceedings of the 2nd Design, Automation, and Test in Europe Conference (DATE'10) (pp. 1-6). Dresden, Germany: IEEE. Retrieved from http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5457142&isnumber=54… A lot of frameworks used in academic work have sort of "standard" citations, people that use the framework tend to cite that paper. The authors get citations, we get cool frameworks, everyone wins.

[libvirt] [Libvirt][Sheepdog]Sheepdog pool/volume storage driver for libvirt problem
by harryxiyou 01 Feb '13

01 Feb '13

Hi Sebastian, Morita and other developers, I have studied Sheepdog pool/volume storage driver for libvirt and i have following questions. Please give me some suggestions. Thanks in advance ;-) 1, In libvirt/src/storage/storage_backend_sheepdog.c, i just find we realized create/delete/resize volume(send these parameters to let libvirtd receive and execute them). I cannot find the operations about snapshot, such as creating/deleting snapshot. I cannot also find the operations about opening/closing cache. 2, In the func create/delete/resize volume, we call func 'virCommandRun(cmd, NULL);' to run these commands, which i think the func send these parameters to daemon libvirtd and libvirtd send these parameters to Sheepdog, then Sheepdog executes them, right? 3, In func "virStorageBackendSheepdogCreateVol", it composes cmd like this "virCommandPtr cmd = virCommandNewArgList(COLLIE, "vdi", "create", vol->name, NULL);" then send create parameters. When Sheepdog receive these parameters, how Sheepdog create this volume? I find Sheepdog create a volume like this. $ qemu-img create sheepdog:Alice 256G 4, What are the essences of func "virStorageBackendSheepdogRefreshPool" and "virStorageBackendSheepdogRefreshVol"? In func "virStorageBackendSheepdogCreateVol", after craete volume operations, we call "virStorageBackendSheepdogRefreshVol". But in func "virStorageBackendSheepdogDeleteVol" and "virStorageBackendSheepdogResizeVol", we do not call "virStorageBackendSheepdogRefreshVol", why? 5, Actually, i am not clear about how QEMU receive these parameters (like create/delete/snapshot, etc) and execute the real jobs? Thanks for anyone's suggestions ;-) -- Thanks Harry Wei

[libvirt] NetworkManager git20121211
by Gene Czarcinski 31 Jan '13

31 Jan '13

I needed some functionality (dynamic dns update) not available in the NetworkManager package available in Fedora 18 so I created my own version based on git20121130. This worked nicely providing the functionality and did not appear to have any bad side effects. Then the NetworkManager git20121211 package appeared in rawhide it is usually better to use a package available from Fedora. So, I got the source rpm and rebuilt it for Fedora 18. This appeared to work fine until I realized that all of the virtual networks did not have the expected IPv4 addresses. Surprisingly, if IPv6 was defined for a network, it was there. After some investigation, I could only see that NetworkManager may be the problem. I downgraded to the git20121130 package and rebooted. The virtual networks were now OK. Any suggestions on how to report this problem? (against what and what release?) I am effectively cross-posting by sending identical messages to the NetworkManager and libvirt mailing lists. Yes, I believe the problem is with NetworkManager but there is a large libvirt impact. Gene

[libvirt] [PATCH 0/2] more work on qemu add-fd support
by Eric Blake 31 Jan '13

31 Jan '13

As promised, here's my first contribution into what is turning into a joint effort between myself and Stefan to support fd passing in qemu 1.3 and newer. Patch 2 in this series is basically a rewrite of Stefan's patch 1/4, and I tested that the capability was successfully set on qemu 1.3 and clear on qemu 1.2. I'm still wondering what we can do to the testsuite to expose more capability testing of qemu 1.2 and beyond (the existing qemuhelptest.c is hard-coded to -help scraping, which limits its usefulness; qemumonitorjsontest looks like a nice way to replay various QMP sessions, but we'd still need to figure out how to capture appropriate sessions from various qemu versions and replay them in the context of qemuhelptest).

[libvirt] [PATCH] tests: add a comment about our fake qmp
by Eric Blake 31 Jan '13

31 Jan '13

While testing QMP, I used a simple qemu session of 'qemu-kvm -M none -nodefaults -nographic -qmp stdio' for some experiments. But it took me far too long to remember the magic invocation to unlock QMP into accepting normal commands. While I was able to grep libvirt sources and easily find where libvirt expects the normal "QMP" greeting, I could not find the proper reply to that greeting nearby. Reading the testsuite didn't help either, since there we don't emulate the mandatory handshake. But since my grep hit the testsuite, adding a bit of documentation will make it much easier to jog my memory in the future. * tests/qemumonitortestutils.c (QEMU_JSON_GREETING): Mention that the normal counterpart reply is skipped. --- tests/qemumonitortestutils.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/tests/qemumonitortestutils.c b/tests/qemumonitortestutils.c index d1b2ab5..7b90c38 100644 --- a/tests/qemumonitortestutils.c +++ b/tests/qemumonitortestutils.c @@ -1,5 +1,5 @@ /* - * Copyright (C) 2011-2012 Red Hat, Inc. + * Copyright (C) 2011-2013 Red Hat, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -439,6 +439,8 @@ static qemuMonitorCallbacks qemuCallbacks = { }; #define QEMU_JSON_GREETING "{\"QMP\": {\"version\": {\"qemu\": {\"micro\": 1, \"minor\": 0, \"major\": 1}, \"package\": \" (qemu-kvm-1.0.1)\"}, \"capabilities\": []}}" +/* We skip the normal handshake reply of "{\"execute\":\"qmp_capabilities\"}" */ + #define QEMU_TEXT_GREETING "QEMU 1.0,1 monitor - type 'help' for more information" qemuMonitorTestPtr qemuMonitorTestNew(bool json, virCapsPtr caps) -- 1.8.1

[libvirt] [PATCH] spec: Avoid using makeinstall relic
by Jiri Denemark 31 Jan '13

31 Jan '13

The macro was made to help installing broken packages that did not use DESTDIR correctly by overriding individual path variables (prefix, sysconfdir, ...). Newer rpm provides fixed make_install macro that calls make install with just the correct DESTDIR, however it is not available everywhere (e.g., RHEL 5 does not have it). On the other hand the make_install macro is simple and straightforward enough for us to use its expansion directly. --- libvirt.spec.in | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 87253c6..8df908d 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1336,7 +1336,11 @@ gzip -9 ChangeLog %install rm -fr %{buildroot} -%makeinstall SYSTEMD_UNIT_DIR=%{buildroot}%{_unitdir} +# Avoid using makeinstall macro as it changes prefixes rather than setting +# DESTDIR.

[libvirt] [Libvirt][Sheepdog]How to test network disk support for sheepdog in Libvirt
by harryxiyou 31 Jan '13

31 Jan '13

Hi all, Morita added network disk support for Libvirt, which supported nbd, rbd, sheepdog, and other protocols. Now, i wanna test network disk support for sheepdog solely. I have following questions. Could anyone please give me some suggestions? Thanks in advance. 1, Before this test, whether should i build the environment of sheepdog or other projects (QEMU)? 2, How could i test network disk support of sheepdog in Libvirt? Which steps should i do for it? 3, Network disk support can support online storage management, right? -- Thanks Harry Wei
